Keyboards are used in almost every type of computer device. Microsoft and Logitech are some of the most popular manufacturers of physical keyboards, but many other hardware makers also produce them.
The keyboard is the computer hardware component that you use to enter text, characters, and other commands on a computer or similar device.
It is an external peripheral in a desktop system (it resides outside the computer case) or is 'virtual' in a tablet PC.
Modern computer keyboards are modeled after, and still closely resemble, classic typewriter keyboards. There are many keyboard layouts available worldwide (such as Dvorak and JCUKEN), but most English language keyboards are of the QWERTY type. Other languages have other standard layouts, such as QWERTZ for German and AZERT for French.
